  • HAZOP – Hazard and Operability study, generally used when identifying hazards for equipment or installations at the design stage.
  • Heat Tolerance – The physiological ability to endure heat and regulate body temperature at an average or better rate than others, often affected by the individual’s level of acclimatization and physical conditioning.
  • Heat Syncope – Collapse and/or loss of consciousness during heat exposure without an increase in body temperature or cessation of sweating, similar to vasovagal fainting except that it is heat induced.
    A heat related condition where blood, which would normally be circulated to the heart and brain, tends to pool in the leg veins, thereby causing fainting. The veins lack tone when initially exposed to hot climates.
  • Heat Stroke – An acute medical emergency caused by exposure to heat from an excessive rise in body temperature [above 41.1°C (106°F] and failure of the temperature-regulating mechanism. Injury occurs to the central nervous system characterized by a sudden and sustained loss of consciousness preceded by vertigo, nausea, headache, cerebral dysfunction, bizarre behavior, and excessive body temperature.
    Heat stroke is caused by exactly the same conditions as heat exhaustion. It begins as heat exhaustion, but when the body’s system for losing heat is overwhelmed the core temperature rises rapidly and tissue damage occurs. This affects mainly the brain, kidneys and liver. The circulation collapses.
  • Heat Stress – The net heat load to which a worker is exposed from the combined contributions of metabolic heat, environmental factors, and clothing worn which results in an increase in heat storage in the body.
  • Heat Strain – The physiological response to the heat load (external or internal) experienced by a person, in which the body attempts to increase heat loss to the environment in order to maintain a stable body temperature.
  • Heat Exhaustion – A heat-related illness characterized by elevation of core body temperature above 38°C (100.4°F) and abnormal performance of one or more organ systems, without injury to the central nervous system. Heat exhaustion may signal impending heat stroke.
    Heat exhaustion is a progression from heat cramp and it is more severe condition. It is more likely in the dehydrated, unfit, the elderly and those who have high blood pressure. It is caused by both salt and water loss.
  • Heat Cramp – A heat-related illness characterized by spastic contractions of the voluntary muscles (mainly arms, hands, legs, and feet), usually associated with restricted salt intake and profuse sweating without significant body dehydration.
    Occurs after prolonged vigorous exercise especially in hot climates. There is a sudden onset of pain and cramps in the extremities. There may be nausea and hypotension and in some cases hyperventilation.

  • Hazards and effects register (Risk Registers) – A record that demonstrates that all hazards and effects have been identified, are understood, and are being properly controlled. This Register is kept current throughout the life cycle of a project or activity, i.e., from the planning and design stage, through operation, to decommissioning, abandonment, and disposal. The term HEMP is being replaced by the Risk Assessment Process.
  • HAZID – Hazard identification. A structured technique used to identify hazards.
  • HAZOP – Hazard and operability. The application of a formal systematic detailed examination of the process and engineering intention of new or existing facilities to assess the hazard potential of operation outside the design intention or malfunction of individual items of equipment and their consequential effects on the facility as a whole.  The HAZOP technique was “defined” in the Chemical Industries Association Code and updated more recently in the CCPS Hazard Identification Procedures.
